Piezoelectric characteristics of electrospun polyvinylidene fluoride/3rd generation hyperbranched polyester blend nanowebs

•This study focuses on the suitability of using electrospun neat PVDF and PVDF/aliphatic HBP of 3rd generation (HBP-G3) blend (90/10) nanowebs as piezoelectric sensors.•Synthesis of HBP-G3 was carried out by one-shot melt-polycondensation method and characterized using FTIR, NMR, TGA and DSC.•Electrospinning of neat PVDF and PVDF/HBP blend (90/10) solutions were carried out, and the nanoweb samples were characterized using FTIR-ATR and XRD measurements.•Compared to neat PVDF (Vp-p = +0.95 V), PVDF/HBP-G1 (90/10) blend exhibited higher Vp-p (+1.62 V), and has the potential for use in energy-harvesting applications.
